Discussion Overview

The discussion revolves around the energy transferred to electrons and the implications when that energy is insufficient to induce a quantum leap. Participants explore whether this energy results in changes to momentum or energy, particularly in the context of electrons in atomic orbitals versus free electrons.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants inquire about the fate of energy transferred to an electron when it is insufficient for a quantum leap, questioning if it merely results in a change of momentum.
  • There is a clarification regarding whether the discussion pertains to electrons in atomic orbitals, with some suggesting that quantum leaps are specifically related to energy levels defined by these orbitals.
  • One participant asserts that any interaction with a photon must affect the energy of an electron, challenging the conditionality of the initial question regarding energy transfer.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between energy transfer, momentum, and energy changes in electrons, indicating that multiple competing perspectives remain without consensus.

Contextual Notes

The discussion does not resolve the assumptions regarding the nature of electrons (free vs. bound) and the specific conditions under which energy transfer occurs.

What happens to the energy transferred to, say, an electron, if it is not enough to affect a quantum leap?
Is it merely transferred to a change of momentum?

Are you referring to electrons in atomic orbitals?

If it changed the electron's momentum, it will certainly change it's energy too.

Unless you can apply excited states to free electrons, then yes, since quantum leaps are only attributed to the energy levels defined by such "orbitals" in my understanding.

I don't see how any interaction with a photon CANNOT affect the energy of an electron. Please explaion what you mean by "If".
